Solution
Explanation
Magnetic lines of force lines are curved lines that are used to describe the direction of a magnetic field which is represented by the tangential on the curved lines.
These lines do not exist; instead, they are hypothetical lines that explain the magnetic field pattern.
The direction of the imaginary magnetic field lines outside the magnet is from north to south and inside the magnet is from south to north.
The two magnetic field lines do not intersect because if they did, the compass needle would be indicating two different directions at the place of intersection, which is impossible.
Therefore, magnetic lines do not cross over each other.
An illustrative diagram shows the direction of the magnetic field in two different directions at the point of intersection.
